^^ Yup. It's a good video. Worth purchasing the entire DVD (on Amazon).
All of what LeeD says is covered in the video. For example, the reason your hand is high is related to your knee bend without getting into "set to launch", because in set to launch, you will be tilting your shoulder back and your hip will bow out (all the same movement). This will automatically lower your racquet. It will be impossible to lower your racquet in the position you achieve before serve.
